IMPORTANT PRECAUTIONS

1.Read all documentation before operating your equipment.
2.Retain all documentation for further reference.         
3.Mains voltage must correspond to rear unit label. 
4.Damages caused by connecting to improper AC voltage are not covered by any warranty.       
5.Always operate the unit with the AC ground wire connected to the electrical system ground. 
   Precautions should be taken to avoid equipment faulty, improper or inefficient grounding.  
6.After connection to power supply Standby LED is lit, showing that some components inside are 
   already powered.
7.Do not connect any amplifier channel output into another channel input. Do not connect in parallel or 
   series an amplifier output with any other amplifier output.          
8.In system setup, amplifier's output power should be 50% greater than loudspeaker(s) rated  handling 
   power.  
9.Make sure the signal is correctly connected to amplifier input channel following current input mode.       
10.Please turn off the power switch when extracting the power cord and signal cable, or adjusting the 
     input mode switch.
11.In order to split one signal to more than one amplifier, we suggest to use a signal distributor.
12.In typical use, please set the volume to -0dB position.        
13.If you need to supply power to more than one unit power amplifiers,to eliminate the big surge current 
     interference to electricity net, and preventing the voltage fluctuate abnormal when simultaneously 
     switching on the amplifiers, we recommend you use the sequence power procedure.
14.Do not obstruct the air entrance and exit ports.
